IMPROVEMENT IN ROTARY CHROMATIC HAND-STAMPS.

lpocltlcntion forming put of Letters Patent. No. 168ml, dlted December 22.1874; application tilt-d November 7, 1874.

To all whom it may concern:

110 it known that. I, Unmuzs ii. BALDWIN, ot'thc city, county, and State of New York, have invented a new and Improved Rotary (hromatic Hand-Stamp, of which the follow in: is a specification:

The invention will first be fully described, and then pointed out in the claim.

Figure 1 represents a side view of my invention. Fig. 2 is a plan of the same.

Similar letters of reference indicate correonding parts.

In the case here presented the letter A represents a cylinder, on which the type is set. The said cylinder has its bearings in the arms of the frame l3, and is held from making more than one revolution by the springcateh U, whieh strikes against a pin or lug on the cylinder end. The ink and color rollers rest in slots 1) on the are, forming bearings for them to revolve in, and are held in such position by elastic bands I), attached to rings slipped over their ends, aml to a ring, set over each end of the type-cylinderjournals, as shown in Fig. 1. I" 1* l I represent notches or rests. into which such rollers as are not required to be used are lifted, so as to clear them from the type-cylinder.

The drawing represents the device ready for printing in blue, red, and green, and showing the other rollers lil'ted out of connection with the type. It will thus be seen that by having a set of rollers varied in form and osition on the are I am enabled to print any number of colors atone time with a single movement forward across the paper; but when it is desired to print in black or any single color, then it will be necessary to use a single roller, as t} or II, and raise all the others oil the type-(y linder into their respective rests I, thus eoinbining a chromatic and plain style of printing in out evice without taking anything oil of or adding anything to the roller-stamp, whieh is operated by grasping the handle I and pushing;' it forward in direction of arrow until the springeatch strikes its stop on the cylinder end. The rollers, or such part or parts of them desired to contain the ink or color, are wrapped with flannel or its equivalent, so as to absorb asufiicient amount of coloring material to feed the type uniformly.

Having thus described my invention, I claim as new, and desire to secure by Letters Iatent- A hand printing-stamp provided llll several inking-rolls, (I II, each connected with the axis of type-roll by springs 15 E, and made to rest with theirjournals either in bearings F or D, as and for the purpose described.

CHARLES E. EALDWIN.
